Our products include: Plastic Extrusions PVC Plastic Edge Trim Rubber Edge Trim Rubber Extrusions Co-extruded Trim Seal Bulb Trim Seal Push-on Trim Seal Rubber Edge Trim Seal EPDM Sponge Rubber Seal D-shaped Rubber Seal P-shaped Rubber Seal Ribbed style Rubber Seal Rubber and Plastic Profiles Sponge Rubber Profiles Edge Protectors Edge Trims, Rubber + PVC Trim Seals, Co-Extruded Profiles Gasket Sealing Profiles Rubber Edge Sealing Self-clamping Gasketing Edge Protection Profiles Edge Protection Sealing Profiles Self-gripping Sealing Profiles Clip-on Sealing Profiles EPDM Rubber extrusions can be spliced and vulcanized to form an endless variety of shapes. Our extensive splicing capabilities allow us to produce seals and gaskets for a broad array of aerospace, automotive, chemical processing, construction, food processing, industrial, oil and gas, as well as wire and cable applications. We have the capability to splice / joint rubber extrusions for applications that require a continuous seal – solid rubber extrusions, sponge rubber extrusions, co-extruded trim seals. When designing a spliced seal, the key consideration is the physical integrity of the joint. Our capabilities support cold and hot splicing as well as transfer and molded splicing. Cold Splicing Simply a matter of gluing two or more pieces of a seal together using quick-setting glue such as cyano-acrylate or super glue. Cold splicing is generally less expensive, depending on the design of the seal and the complexity of the cross section. Hot Splicing Considered to be the industry standard and most desirable when cosmetics are a concern. The glue used in hot splicing is rubber-based and has to be cured, or vulcanized, in place. This creates a splice that has reasonable strength, retains properties of the seal, and is inconspicous. Injection Splicing Works similar to injection molding. A mold is created so that two or more pieces of a seal can be inserted into the tooling. A polymer is then injected or transferred into the mold cavity, adhering the ends of the seal and creating a continuous seal or multi-sided gasket. The process allows for much greater detail work on the seal, producing a splice that is aesthetically pleasing.
